Maraga Observatory
Maragheh () is a city in the Central District of Maragheh County, East Azerbaijan province, Iran, serving as capital of both the county and the district. Maragheh is on the bank of the river Sufi Chay. It is from Tabriz, the largest city in northwestern Iran. History Pre-Islamic history It has been long suggested that Maragheh is identical with Phraaspa/Phraata, the winter capital of Atropatene. The 9th-century Muslim historian al-Baladhuri (died 892) reports that the town was originally known as Akra-rudh (called "Afrah-rudh" by Ibn al-Faqih, and "Afrazah-rudh" by Yaqut al-Hamawi) a Persian name which means "river of Afrah", and which the Russian orientalist Vladimir Minorsky considered to seem reminiscent of the name of Phraata. He added that it is unlikely that Maragheh did not exist during the Roman era, due to its favorable location.

Nizari Ismaili State
The Nizari state (the Alamut state) was a Nizari Isma'ili Shia state founded by Hassan-i Sabbah after he took control of the Alamut Castle in 1090 AD, which marked the beginning of an era of Ismailism known as the "Alamut period". Their people were also known as the '' Assassins'' or ''Hashashins''. The state consisted of a nexus of strongholds throughout Persia and the Levant, with their territories being surrounded by huge swathes of hostile as well as crusader territory. It was formed as a result of a religious and political movement of the minority Nizari sect supported by the anti- Seljuk population. Being heavily outnumbered, the Nizaris resisted adversaries by employing strategic, self-sufficient fortresses and the use of unconventional tactics, notably assassination of important adversaries and psychological warfare. They also had a strong sense of community as well as total obedience to their leader. Despite being occupied with survival in their hostile environment ...

Muslim World
The terms Islamic world and Muslim world commonly refer to the Islamic community, which is also known as the Ummah. This consists of all those who adhere to the religious beliefs, politics, and laws of Islam or to societies in which Islam is practiced. In a modern geopolitical sense, these terms refer to countries in which Islam is widespread, although there are no agreed criteria for inclusion. The term Muslim-majority countries is an alternative often used for the latter sense. The history of the Muslim world spans about 1,400 years and includes a variety of socio-political developments, as well as advances in the arts, science, medicine, philosophy, law, economics and technology during the Islamic Golden Age. Muslims look for guidance to the Quran and believe in the prophetic mission of the Islamic prophet Muhammad, but disagreements on other matters have led to the appearance of different religious schools of thought and sects within Islam.

Waqf
A (; , plural ), also called a (, plural or ), or ''mortmain'' property, is an Alienation (property law), inalienable charitable financial endowment, endowment under Sharia, Islamic law.

A charitable trust may hold the donated assets. The person making such dedication is known as a ('donor') who uses a ''mutawalli'' ('trustee') to manage the property in exchange for a share of the revenues it generates. A waqf allows the state to provide social services in accordance with Islamic law while contributing to the preservation of cultural and historical sites. Although the system depended on several hadiths and presented elements similar to practices from pre-Islamic cultures, it seems that the specific full-fledged Islamic legal form of financial endowment, endowment called dates from the 9th century CE (see below ...

Siege Of Baghdad (1258)
The siege of Baghdad took place in early 1258. A large army commanded by Hulegu Khan, Hulegu, a prince of the Mongol Empire, attacked Baghdad, the historic capital of the Abbasid Caliphate after a series of provocations from its ruler, caliph al-Musta'sim. Within a few weeks, Baghdad fell and was sacked by the Mongol army—al-Musta'sim was killed alongside hundreds of thousands of his subjects. The city's fall has traditionally been seen as marking the end of the Islamic Golden Age; in reality, its ramifications are uncertain. After the accession of his brother Möngke Khan to the Mongol throne in 1251, Hulegu, a grandson of Genghis Khan, was dispatched westwards to Greater Iran, Persia to secure the region.

Mongol Campaign Against The Nizaris
The Mongol campaign against the Nizaris of the Alamut period (the Nizari Ismaili state) began in 1253 after the Mongol invasion of the Khwarazmian Empire and a series of Nizari–Mongol conflicts. The campaign was ordered by the Great Khan Möngke and was led by his brother, Hülegü. The campaign against the Nizaris and later the Abbasid Caliphate was intended to establish a new khanate in the region—the Ilkhanate. Hülegü's campaign began with attacks on strongholds in Quhistan and Qumis amidst intensified internal dissensions among Nizari leaders under Imam Muhammad III of Alamut whose policy was fighting against the Mongols. His successor, Rukn al-Din Khurshah, began a long series of negotiations in face of the implacable Mongol advance. In 1256, the Imam capitulated while besieged in Maymun-Diz and ordered his followers to do likewise according to his agreement with Hülegü. Despite being difficult to capture, Alamut ceased hostilities too and was dismantled. The Niz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abbasid Caliphate
The Abbasid Caliphate or Abbasid Empire (; ) was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib (566–653 CE), from whom the dynasty takes its name. After overthrowing the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132 AH), they ruled as caliphs based in modern-day Iraq, with Baghdad being their capital for most of their history. The Abbasid Revolution had its origins and first successes in the easterly region of Khurasan, far from the Levantine center of Umayyad influence. The Abbasid Caliphate first centered its government in Kufa, modern-day Iraq, but in 762 the caliph al-Mansur founded the city of Baghdad as the new capital. Baghdad became the center of science, culture, arts, and invention in what became known as the Golden Age of Islam.
